7 Claims. (Cl. 132--33) This invention relates to certain improvementsin hair waving devices in which a pre-formed tress of hair is subjectedto the action of an exothermic material which, when moistened, will of15 itself generate heat sufficient to impart a socalled permanent waveto the tress.

This invention comprises a hair waving device in which a charge ofexothermic material is inserted into a tube of absorbent material, thecharge being either in the form of a soluble capsule containing theexothermic material or a'rod of exothermic material or a coiled sheetimpregnated with the exothermic material; a perforated tube of metal orother suitable stifi material being preferably used to provide a rigidsupport for the wound tress.

Practical embodiments of my invention are represented in theaccompanying drawings, in which:

Fig. 1 represents the hair waving device in side elevation as in use;

Fig. 2 represents a longitudinal central section through the same, thecharge of exothermic material being in the form of a soluble capsulecontaining the exothermic material and the tress being wound on aperforated tube of stiff material;

Fig. 3 represents a similar view in which the charge of exothermicmaterial is in the form of a rod;

Fig. 4 represents a similar view in which the charge is in the form of acoiled sheet impregnated with the exothermicmaterial;

Fig. 5 represents a similar view with the exception that the tress iswound on the tube of absorbent material and the perforated tube isinserted between the absorbent tube and a soluble capsule containing theexothermic material;

Fig. 6 represents a similar view except that the charge of exothermicmaterial is in rod form;

Fig. '7 represents a similar view except that the charge of exothermicmaterial is in the form of a coiled sheet impregnated with theexothermic material;

Fig. 8 represents a similar view in which the hair tress is wound on thetube of absorbent material, the perforated tube between the tube ofabsorbent material and the soluble capsule containing the exothermicmaterial being omitted;

Fig. 9 represents a similar view with the exception that the charge ofexothermic material is in the form of a rod; and

Fig. 10 represents a similar view with the exception that the charge ofexothermic material is in the form of a coiled sheet impregnated withthe exothermic material.

The outer wrapper is denoted by 1, which wrapper may be made of anysuitable non-absorbent material, such as parchment paper, foil 5 or thelike. The clamp is denoted by 2, which clamp may be of any well known orapproved form. It is to be understood that any suitable protective pad(not shown herein) may be inserted between the clamp 2 and the scalp ofthe 10 person being treated.

The perforated tube is denoted by-3, which tube may be made of metal orother suitable stifi material. The tube of absorbent material is denotedby 4, which tube is adapted to be mois- 15 tenet]. by water or by asuitable hair waving solution such as that used formoistening the tress.The charge of exothermic material may be in various forms For instance,it may be in the form of a-soluble capsule 5 containing the exo- 20thermic material 6 in powdered form, a suitable exothermic materialbeing calcium oxid. An-

.other form of charge may be a rod 7 of the exothermic material. Stillanother form of charge may be a coiled sheet 8 impregnated with theexothermic material.

In the forms shown in Figs. 2, 3 and 4, the tress of hair 9 is woundupon the perforated tube 3 and the tubeof absorbent material is insertedbetween the charge of exothermic material and the said perforated tube.

In the forms shown in Figs. 5, 6 and '7, the tress 9 is wound upon thetube 4 of absorbent material and the perforated tube 3 is insertedbetween the charge of exothermic material and the said tube of absorbentmaterial.

In the forms shown in Figs. 8, 9 and 10, the tress 9 is wound upon thetube 4 of absorbent material and the perforated tube 3 is omitted, thecharge of exothermic material being inserted directly into the bore ofthe tube of absorbent material.

In practice, the tress 9 is wound either upon the perforated tube 3 asshown in Figs. 2, 3 and 4 or on the tube 4 of absorbent material asshown 40 in Figs. 5 to 10 inclusive. The tress 9 may be moistened eitherbefore or after it is wound, by a suitable waving solution, such forinstance as an ammonia solution. The tube 4 of absorbent material ismoistened by water or by a suitable hair, waving solution such as thatused for moistening the tress 9.

The charge of exothermic material may then be inserted into the bore ofthe moistened tube of absorbent material in the forms illustrated inFigs. 2, 3, 4, 8, 9 and 10 or into the bore of the perforated tube asshown in the forms illustrated in Figs. 5, 6 and 7. The outer wrapper 1is then wrapped around the wound tress and may be secured at the scalpend of the tress by the clamp 2, the outer end of the wrapper beingtwisted together to close the same.

In the case where the charge is in the form of a rod of the exothermicmaterial or in the form of the coiled sheet impregnated with theexothermic material, the exothermic action starts at once because of theapplication of moisture by the wetted tube of absorbent material to theexothermic material.

In the case where the exothermic material is contained in a solublecapsule the first action of the moisture of the wetted tube of absorbentmaterial will be to dissolve the capsule and thus bring the moistureinto contact with the exothermic material to start the exothermic actionwithin the device.

In all of these instances heat is set up within the device sufiicient toimpart a so-called permanent wave to the pre formed tress withoutrequiring application of heat from an outside source.

It will be seen that the outside wrapper serves to confine the heat to alarge extent within the device, the steam generated by the reaction ofthe water and/or waving solution with the exothermi'c material beingpermitted to escape through the crimped outer end of the said wrapper.

The forms of hair waving device including the rod of exothermicmaterial, shown and described but not claimed herein, form the subjectmatter of my divisional application filed February 15, 1933, Serial No.656,794.

The forms of hair waving device including the coiled sheet impregnatedwith exothermic material, shown and described but not claimed herein,form the subject matter of my divisional application filed February 16,1933, Serial No. 656,985.

It is evident that various changes may be resorted to in theconstruction, form and arrangement of the several parts withoutdeparting from the spirit and scope of my invention, and hence I do notintend to be limited to the particular embodiments herein shown anddescribed.

What I claim is:

1. A hair waving device comprising a perforated tube and a tube ofabsorbent material telescoping one within the other, and around whichthe tress is to be wound, and a soluble tube containing an exothermicmaterial, insertable within the perforated tube and tube of absorbentmaterial.

2. A hair waving device comprising a perforated tube on which the tressis to be wound, a tube of absorbent material insertable into theperforated tube and adapted to be moistened, and a charge of exothermicmaterial insertable into the absorbent tube.

3. A hair waving device comprising a perforated tube on which the tressis to be wound, a tube of absorbent material insertable into theperforated tube and adapted to be moistened, and a charge of exothermicmaterial insertable into the absorbent tube, said charge being encasedin a soluble capsule.

4. A hair waving device comprising a tube of absorbent material adaptedto be moistened and around which the hair tress is to be wound, and acharge of exothermic material insertable into the said absorbent tube.

5. A hair waving device comprising a tube of absorbent material adaptedto be moistened and around which the hair tress is to be wound, and acharge of exothermic material insertable into the said absorbent tube,said charge being encased in a soluble capsule.

6. A hair waving device comprising a tube of absorbent material adaptedto be moistened and around which the hair tress is to be wound, aperforated tube telescoping within the absorbent tube, and a charge ofexothermic material insertable into said perforated tube.
